I'd had brain tumor surgeries before my BC diagnosis. The neurosurgeon had told me back then that "people who have one type of cancer are more likely (than others) to have another type of cancer." After 2nd Brother was diagnosed/treated for colon cancer, I found a cluster called HNPCC that seems to explain our family cancer history (Mother has had Non-Hodekins Lymphoma.)

One time when I was feeling discomfort in my right lower abdomin area and the doctor sent me to ultrasound after CT-scan - I was so very sure that I'd had liver mets. It turned out to be harmless 'hepatic hemangioma'. So hang in there - don't scare yourself too much.
